Offer to save passwords on insecure HTTPS sites

Hello,

For server administrator of various company-specific websites (example a customer's UniFi installation, or Ubiquiti AirControl, or similar apps/services) we historically use Firefox. Firefox will permit the saving of a login password of a website, even if the site uses a self-signed or untrusted SSL certificate. This is very valuable to us, and Edge should have an option to enable the same. That is, not all untrusted SSL certificates are bad, and an option should be given to allow saving credentials even when visiting a site with an untrusted cert. Thanks.
